Trichormus azollae a species of filamentous, heterocyst-forming cyanobacterium that is involved in symbiosis with various plants in the genus Azolla such as Azolla filiculoides.[1]
In terms of 16S RNA, the strain found in A. filiculoides is very close to Anabaena oscillarioides with 99.3% identity.[2] The many "Azolla cyanobiont" 16S sequences as recorded on NCBI GenBank do not neatly form a cluster that excludes other named cyanobacterial species; high-identity (> 98.7%) matches include Anabaena azotica and Wollea saccata.
The genome of a strain known as 0708, isolated from A. filiculoides, has been sequenced.[3] Contrary to 16S comparison results, GTDB Release 10 does find enough genomic diveregence between A. azotica (Trichormus azoticus) and T. azollae (Trichormus_B azollae) for them to be separate species. It goes further to put them in separate genera.[4]
